A hemispherical-cup anemometer of the type invented in 1846 by John Thomas Romney Robinson. In meteorology, an anemometer (from Ancient Greek άνεμος (ánemos) 'wind' and μέτρον (métron) 'measure') is a device that measures wind speed and direction. It is a common instrument used in weather stations.
Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction
In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and is known as the first anemometer. [1] In 1607, Galileo Galilei constructs a thermoscope. In 1643, Evangelista Torricelli invents the mercury barometer. [1] In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge.
An anemoscope c1920s built by the American instrument maker Julien P. Friez & Sons is in the collection of Harvard university was designed to be used as part of an automatic wind recorder alongside a wind speed measuring anemometer. [3] Today anemoscopes are used in meteorological stations, and in transport especially boats.
Anemometer, weather vane, anemoscope A windsock (a wind cone or wind sleeve) is a conical textile tube that resembles a giant sock . It can be used as a basic indicator of wind speed and direction , or as decoration.

Jamie's mother and father, too, have hung onto other mementos like pictures, dolls and the checkerboard used to play games with her father. "She is part of history, and I want people to know that ...
Eddy covariance system consisting of an ultrasonic anemometer and infrared gas analyser. The eddy covariance (also known as eddy correlation and eddy flux) is a key atmospheric measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers.
